I am Saravanan. I am interested to study oracle performance tuning course but I did not know which one is best so i searched on web i saw GangBoard In first page then i checked reviews. Reviews were good. So i joined in GangBoard. My trainer was vinothkumar. He was working on one of the IT Company. He teaches well and gave practical training and showed live projects, real time examples and helped more. Now i have confidence to work on oracle performance tuning.
